Three subgroup common transversal in abelian groups
Maria Loukaki, Emmanouil Spyridakis
We completely characterize when three equal-order subgroups of a finite abelian group share a common transversal. Consequently, we determine when three full-rank lattices of equal…

Bounded and measurable common fundamental domains for two lattices
Emmanouil Spyridakis
Suppose that are two full-rank lattices in Euclidean space with . We give a new proof on the existence of a bounded and Lebesgue measurable set…
